We are still searching for game pictures and screenshots for Wolf of the Battlefield: Mercs (Nintendo Wii). We do not have any cheats, codes, or hints yet.

At the options screen, highlight Original Mode, then hold A, B, C, and then press Start.

If you beat Mercs on original mode (not the arcade version) you will see in the end that they will show you where all the hidden areas are in game for each level on original mode.
